EPR Spectrometer for Probing Biomimetic Metal Sites

摘要

An EPR spectrometer was purchase with funds obtained with DURIP grant N00014-998-0448. This instrument, which has been operational since November 1998, has been used to characterized structure/functional properties of new materials. These materials are used for gas storage/release and transport, sensors and catalysis. Materials that rapidly and reversibly bind O2 and NO have been fabricated. Biomedical applications include artery (smooth muscle) relaxation under biologically relevant conditions which is induced by the release of NO from an NO-containing polymer. Platelet formation is also inhibited by this NO-releasing material.
